METAL FRAME FOB OPENINGS.

Application filed April 16, 1928. Serial No. 270,851.

My invention relates to the building art and particularly to metal framing for wall openings.

It is well known in the trade to provide metal or wood devices to define a wall 0 ening, but in my experiencemany object1ons have arisen to the use of-these devices, for various practical reasons.

In a device of the character required, it 1s necessary to provide a device that will insure perfect anchorage with the tile'or brick adjacent to the opening, there must be perfect alignment, and a strong corner bead, as well as complete rigidity of the entire unit. These requisites are wholly orpartlally lacking in the opening frames heretofore observed, and it is an object of my invention to provide these and many other structural advantages;

It is of the utmost importance in a devioe'of this character to provide means for insuring accurate installation by an inexpert workman, and I have endeavored to so construct 'thls device that it can be installed quickly by only a few simple movements.

A further object of my invention is to pro vide means for maintaining a firm plaster ground in conjunction with the opening frame, which iseasily and firmly secured by a simple movement.

Another object of my invention is to provide means associated with the frame, for an anchor which is inserted between the tile in positioning the frame.

These and further objects will appear from --a further study of the drawings, attached hereto and made a part hereof; in which- Fig. 1 is a perspective view of a corner of a metal frame constructed in accordance with my invention;

Fig. 2 is a horizontal sectional view thereof;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 2;

Fig. 4 is a horizontal sectional view of a modification of the corner construction;

Fig. 5 is a vertical sectional view taken on the line 55 of Fig. 4; and

Fig. 6 is a vertical sectional view taken on the line 33 of Fig. 2 showing a modified form of anchor.

By reference to the drawings and particularly to Fig. 1, it will beseen that my invention comprises the vertical frame member 10, the horizontal frame member 11, and the right angle joining member 12. The joining memzontal member 11. .The frame members each have angularly disposed marginal flanges 14,

15, 16, 17 terminating in the backwardly bent.

corner beads 18, 19, 20, 21 which serve as a plaster defining gauge and corner bead.

For insuring a firm connection between the two right angularly disposed framememhers, I provide the tongues, 22, 23 struck out from the web of the horizontal portion of the member 12, and projecting through slits 1n the frame member 11. When these tongues are bent toward the vertical member they provide a very strong and secure lock against lateral movement.

As a means for insuring perfect alignment of the two frame members with-the tile adjacent the opening, I provide the ears 24, 25, 26, 27 bent at right angles to the frame members, the anchor 28, shaped in the form of a be readily'secured tothe inner faces of the channels by hooking over the lugs.

A modified form of anchor attached to the vertical channel, is shown in Figs. 1 and 6, which consists of the longitudinal slot 34 extending vertically in the web of the channel 10, and adapted to receive the anchor 35, having the two notches, 36, 37 a short distance below the end head 38. This anchor is secured by merely inserting the notched end into the slot and turning the anchor to cause tile notches to fit over the inner edges of the s ot.

A further modified form of the corner joint is illustrated in Figs. 4 and 5 wherein the nuts and bolts 39, 40 are used instead of the tongues 22, 23 to insure a more rigid and permanent fit. Also the beads 20 and 21 are bent inward instead of outward as shown in Fig. 1, to serve as a guidin and retaining unit for the flanges of the ent member 12 which are received therein.

The form illustrated in Figs. 4 and 5 is the and permanent, thus avoiding the possibi of inaccuijte work.

Thus it is seen that I have rovided a metal frame for o enings that em odies all of the requisites 0 a satisfactory device for the purose intended.- The anchors provide a firm flt with the tile adjacent the opening, the ears insure perfect fit and alignment, the lugs provide a means of securing the plaster ground, and the angularly disposed corner beads provide a plaster defining unit, as well as a corner protection.

Obviously modifications and variations ma be made in the device herein disclosed an I do not wish to be limited except as indicated in the appended claims.

I claim: 1
